Cant view products under categories in magento 2.4.3

Im trying to upgrade our magento commerce site from 2.4.1 to 2.4.3 in a staging environment – Ive almost got it working but Ive found that when navigating through the category tree at the lowest level no products are being displayed just the message

We can’t find products matching the selection.

Ive seen this before and tried all the usual suggestions

• reindex
• clear cache
• flush cache
• purge front page cache

With no luck. Searching for products and viewing results works fine.

Ive also tried solutions posted here

This has lead me to find that there is an issue editing product attributtes in the admin section, I get a js error on load of the attributtes, the data loads but I cannot save them.

Uncaught TypeError: Cannot read property 'show' of undefined

I have tried setting the attributes to non filterable and none searchable at SQL level but no luck.

This works fine in 2.4.1, and the only change is the upgrade

any ideas?
